Before this gets out of hand, I'd like to point out what has already been said. But in a different colour.
Once the mod updates, you can request to have your base relocated (if the system was subjected to changes), see HERE. It is the Player-Owned Base owner's responsibility to submit any request after such a change. The staff are not in charge of following up on all bases. If the owner fails to do so, and their base has now been the target of a siege, that opportunity for relocation has been temporarily voided until the siege gets resolved.
I choose those specific words, because you can try to request it if your base survives the siege, but be warned that your chances are much smaller due to the time gap. If you have had a team or friends to supply the base since the patch, and had noticed a hostile NPC base within scanner range of your base and made no request... well, I don't have much more to add.
As I said, it's the base owner's responsibility.
Hope your base survives. Good luck.
We will be monitoring the thread, if it goes downhill further, we will lock it down. You have been warned.
